A number of Dell Inc. employees working for Harvard Pilgrim Health Care’s Quincy offices are reportedly being let go as the company shifts their technology service operations.

Joan Fallon, director of public relations and community affairs at Harvard Pilgrim, said the affected employees do not work for Harvard Pilgrim, but are employed by Dell for information technology work at the insurer’s Quincy office.

Dell spokesman David Frink said fewer than 1,000 people in the company’s global workforce had been affected by layoffs, including some in the Boston area. Frink wouldn’t specify the locations or employees affected. Frink went on to say that the reduction was being done to "improve our efficiency and optimize our operation."

Harvard Pilgrim, a health benefits company serving over 135 hospitals and 28,000 doctors and clinicians throughout New England, has been outsourcing their IT services for decades, with Texas-based Perot Systems Corp. managing portions of Harvard Pilgrim’s information technology and claims processing since 1999.

In 2008, Perot entered into a 13-year, $1 billion contract with Harvard Pilgrim to handle additional claims and back-office operations.

Harvard Pilgrim subsequently cut upwards of 84 jobs, transferring most of those employees to Perot. At the time, the Boston Business Journal reported that Perot employed 500 people to handle IT work for Harvard Pilgrim, majority based out of Quincy.

In 2009, computer maker Dell Inc. purchased Perot for $3.9 billion, the largest acquisition in Dell’s history at the time.

Despite shifts, Frink said Dell had appropriate teams in place to ensure customer service wouldn’t be affected by recent events, and said the company continued to expand overall.

“We continue to hire in the U.S. and around the world in various areas of our business,” he said.
